cougard Posted December 10, 2008 Share Posted December 10, 2008 Hi all, I seem to have developed an engine stutter/lack of power. Its a 110 2001 TD5. The problem suddenly started on my way back home one night. It drives fine in the lower rev range but starts to stutter and produce very little power in the higher rev range. I have replaced the injector loom back in July and cleaned out the plugs on the ECU. I will look for signs of fresh oil at the injector loom plug tonight. Anyone have any ideas on where to look next? Thanks, Matt.. Quote Link to comment Share on other sites More sharing options...
Tonks4x4 Posted December 10, 2008 Share Posted December 10, 2008 Check to see if the fuel pressure regulator is leaking Change fuel filter just as a precation Quote Link to comment Share on other sites More sharing options...

Thanks, Matt.. Matt... It could be a few things. Check the injector loom as you have already mentioned. My next port of call would be to look at the turbo - and in particular the wastegate. Td5 turbo have a habit of suffering from sticky wastegates -when this happens it causes overboost (i.e. higher pressure than expected) so the ECU cuts the fuelling until boost pressure is back below the limit. To check the wastegate, clamp a set of mole grips on the none threaded part of the wastegate actuator and try and extend the arm towards the bulkhead. If it doesn't move, or is very stiff.... remove the heat shield around the turbo, and unclip the actuator arm from the wastegate (small 'C' clip). Then try and move the wastegate arm itself separately... it should move with little or no force. If stiff or seized, give it a good soaking in WD40 and then try and free it off. Once freed off, refit the wastegate arm and go for a drive. Ian Quote Link to comment Share on other sites More sharing options...
BogMonster Posted December 11, 2008 Share Posted December 11, 2008 I'd check the fuel pressure too, the fuel pump might be working but on the way out and this usually pops up when you ask it for lots of fuel. Quote Link to comment Share on other sites More sharing options...
cougard Posted December 11, 2008 Author Share Posted December 11, 2008 Thanks all. I have a feeling its going to be the pump on the way out. It was making a nice humming noise a few days back but now it is suspiciously silent . I did put my ear to the floor of the rear tub and cant hear a sound. Is there an easy way to check if the pump is working? What id i disconnect the fuel line from the side of the filter and turn the ignition on? Thanks, Matt.

BogMonster Posted December 11, 2008 Share Posted December 11, 2008 Yep - stick your ear to the tank like you just did If there is nothing at all then either the pump is f***ed or there is no power to it. You can normally hear a quiet hum, before it expires this often increases for a short time to a noise which sounds rather like a cat being fed through a mangle tail first (wheeeaaarowwwwowowowowoww), then goes quiet. Bear in mind the pump only runs for a short time (about 30 sec) after you switch the ignition on. The bad news is that you need to either take the tank out or cut a hole in the floor to access the pump. The measurements for doing this cut without hitting anything important are elsewhere on the forum (I am not sure if it is in here, or in the Tech Archive, or in the International forum, but one of the three...) Check power/earth to the pump before you fork out a couple of hundred beer tokens for a new one, but if it is not running I would say it is 80% likely to be the pump rather than the power to it as they aren't the most reliable thing on the planet.

cougard Posted December 11, 2008 Author Share Posted December 11, 2008 a noise which sounds rather like a cat being fed through a mangle tail first (wheeeaaarowwwwowowowowoww), then goes quiet. That's the most accurate description of the sound! Exactly what it was doing. Looks like new pump time then. Quote Link to comment Share on other sites More sharing options...
ozzie1989 Posted December 12, 2008 Share Posted December 12, 2008 Bear in mind the pump only runs for a short time (about 30 sec) after you switch the ignition on. Forgive me if I'm wrong but doesn't the pump run all the time? Or do the injectors internal pumps carry on pulling the fuel through? Quote Link to comment Share on other sites More sharing options...
calle-fas Posted December 12, 2008 Share Posted December 12, 2008 If you turn the ignition to II, without starting the engine, the pump will only run for about 30 seconds. Quote Link to comment Share on other sites More sharing options...
Andrew Chua Posted December 15, 2008 Share Posted December 15, 2008 yup, so in the morning, when it's all quiet, climb in, put the ignition to pos II, and you'll hear it. usually you should also be able to hear the 2 stage of the pump running, ie the sound changes a little after like 5 seconds. if you hear nothing, then the pump is not running. check the electrics first and if you're sure it's the pump, get a new one. now the fun begins. how to get the old one out and new one in.

cougard Posted December 15, 2008 Author Share Posted December 15, 2008 I have done it the cheats way and cut a hole in the rear tub floor. When I put me ear right to the pump, I can just hear it but it is very quiet. I am going to drop a new pump (well, second hand but working fine) in tonight and see if it solves the problem. Matt.

That change is just because of the jump in voltage when the glow plugs switch off Quote Link to comment Share on other sites More sharing options...
cougard Posted December 16, 2008 Author Share Posted December 16, 2008 Well I have changed the pump and all is well again. Thanks for the help guys. Quote Link to comment Share on other sites More sharing options...
